4Range of ToleranceThe range of environmental conditions in which an organism can live and reproduce.
5Where will you find the greatest diversity? Least # of organisms?
6Are biotic or abiotic factors that LIMIT the growth of a species. ComparisonLimiting FactorsRange of ToleranceAre biotic or abiotic factors that LIMIT the growth of a species.Determined by the limiting factors that affect a species.
7Ecological Succession The process by which an existing ecosystem is gradually and progressively replaced by another ecosystem
8Primary SuccessionThe development of biotic communities in a previously uninhabited and barren habitat with little or no soil.Ex. After lava flow
9Pioneer Species First organisms to appear in primary succession Help to create the soil by secreting acid to break down rockEx. Lichens (fungi/algae combo) & Mosses
10Climax Community A relatively stable collection of plants and animals These will change due to environmental factors such as fires, floods, winds, tsunamis, hurricanes, droughts, and other natural disasters.
11Secondary SuccessionThe development of biotic communities in an area where the natural vegetation has been removed or destroyed but where soil is present.Ex. After a fire
13The establishment of a community in an area with no soil. ComparisonPrimary SuccessionSecondary SuccessionThe establishment of a community in an area with no soil.The establishment of a new community in an existing ecosystem that was disturbed.
14Where are the most pioneer species? What usually appears last?
15BiomesEcosystems identified by their climax community
16ClimateThe average year-after-year conditions of temperature & precipitation in a particular regionThe variation of climate primarily depends upon the angle of incoming sunlight
